introduction
Once again I installed [http://debian.org Debian] on a notebook. This time on a friends [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4L3J5R IBM Thinkpad X20]. This is not exactly spectacular, but I ran into some small problems, which I want to write down as a reference for others.

ingredients
[http://thinkwiki.org/wiki/Category:X20 Thinkwiki.org] tells you something about the ingredients of this notebook.
compatibility
The table below shows compatibility with kernel >= 2.6.15. Everything highlighted in green is fully supported. Orange means particularly supported and everything in red isn't supported at the moment.

installation
There are [http://thinkwiki.org/wiki/Installation_on_ThinkPads_without_CD-ROM_drive several possibilities] to install Debian though it hasn't a built-in CD-ROM drive. The easiest approach is to use an external USB-drive.
The installation of Debian Etch ([http://www.debian.org/devel/debian-installer/ Debian Installer Etch beta 2]) worked smoothly.
configuration
kernel
Because of some problems with Speedstep (have a look at the FAQ) I compiled my own kernel. The [attachment:config .config]-file is slightly different from Debian's standard.
x.org
Nothing spectacular. Here is the [attachment:xorg.conf xorg.conf].
faq
- Speedstep doesn't work
After trying to load speedstep modules the following message appears: FATAL: Error inserting speedstep_smi (/lib/modules/2.6.15-1-486/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-smi.ko): No such device
To get this working you'll need a kernel with this option enabled:
CONFIG_X86_SPEEDSTEP_RELAXED_CHECK = y
That's the case with recent Debian kernels. Go on and disable the speedstep-lib checks by by creating a /etc/modprobe.d/speedstep-lib file with this content:
options speedstep-lib relaxed_check=1
And then, you may add these 2 lines to /etc/modules:
speedstep-lib speedstep-smi
- Speedstep still doesn't work
You have disabled the speedstep-lib checks like explained above, but speedstep still doesn't work with kernels <=2.6.15? It's a [http://bugzilla.kernel.org/show_bug.cgi?id=5553 kernel bug]. Try to enable this kernel option:
CONFIG_CPU_FREQ_DEBUG = y
- Speedstep does work but I can't use ondemand governor
This governor doesn't work work on older laptops without Enhanced Speedstep (and guess: the X20 is a "plain-speedstep" notebook).
- Starting with kernel 2.6.16 my soundcard doesn't work
The alsa driver fails to probe the sound chip:
PCI: Found IRQ 5 for device 0000:00:0b.0 ... never read ISV3 and ISV4 from AC'97 CS4281: probe of 0000:00:0b.0 failed with error -5
It's a [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=361197 bug]. Wait until it'll be fixed or switch back to kernel 2.6.15.
